PyCBC is a software package used to explore astrophysical sources of gravitational waves. It contains algorithms that can detect coalescing compact binaries and measure the astrophysical parameters of detected sources. PyCBC was used in the first direct detection of gravitational waves (GW150914) by LIGO and is used in the ongoing analysis of LIGO and Virgo data. If you use PyCBC in your scientific publications or projects, we ask that you acknowlege our work by citing the papers described on the page:
Get the full PyCBC software suite with one of our Docker Images
If you have Docker installed, you can get started using PyCBC with just two commands:pycbc — bash — 80x25$
For more details, including instructions on starting a container that can display graphics, see:
Use the PyCBC Library within your Browser
We have interactive jupyter notebooks on azure where you can try some of our examples, and use the pycbc library. All from within the browser. Give it a try
Note, if you are a LIGO / Virgo member with access to LDG resources, PyCBC is already installed on your cluster through CVMFS! Instructions to source any release of PyCBC is available from the releases page.
You may also install PyCBC directly with pip. You may ommit lalsuite if you have your own build.
pip install lalsuite pycbc
